a ram INTERLINING BACKGROUND OF THE INVENTION Present-day interliningmaterial designed to be laminated with another layer of fabric forstiffening and/or reinforcing garments, draperies and the like are wellknown. In one commercial form, a fusible resin, distributed as a myriadof closely spaced small dots, is employed to unite the two fabriclayers. Consequently, since plural small areas of adhesion rather than acontinuous film of adhesive are relied on, lamination of the interliningto the adjacent fabric is obtained without the boardy effectcharacteristic of an uninterrupted layer of adhesive.

According to present practice, these dots, or other form of surfaceapplication of the resin, are deposited on the sub-strate in the form ofa paste in the following ways: a

l. The so-called Smith and Nephew method in which a web of thermoplasticresin is prepared of dots joined by links. This web is fed together withand contiguous to the sub-strate and heat is applied. The dimensions ofthe links are such that, upon heat being applied, the softened substanceof the links is drawn toward the dots by capillary attraction toincrease the bulk thereof, and hence the adhesiveaction, withoutrendering the interlining boardy. I

2. The sub-strate is traversed just above the surface of a reservoircontaining the resin in flowable form. A bank of needles is reciprocatedvertically to pass through the sub-strate and dip into the bath. Uponthe return stroke, the resin adherent to the needles is stripped off andremains on the sub-strate as the required myriad of dots.

3. In roller printing, a roller has etched depressions correspondingsubstantially with the ultimate shape of dots. The roller rotatespartially submerged in a bath of resin which is pasty and a doctor bladestrips the excess. The sub-strate is heated and traversed in contactwith the roller, whereby the resin held in the depression is sucked onto the sub-strate by capillary attraction.

4. The sub-strate moves along the periphery of a rotating drum havingperforations of the correct size in its lateral wall. The resin, offlowable consistency, is fed to the interior of the drum, while a doctorblade forces the same through the perforations on to the substrate.

5. A web of resin, e.g. as randomly dispersed fibers adherent at theirintersections, is fed along with the sub-strate and pressed intoadherence therewith by a roller or rollers. Heat may be applied tosoften the web just prior to application of pressure.

6. The sintering method comprises random dispersion, e.g. bysprinkling,of particles of resin on to the heated sub-strate whereto the particlesadhere.

An improved interlining and the method of making the same are disclosedin my co-pending application Ser. No. 179,334, filed Sept. 10, 1971,which is incorporated in the present specification by reference.

SUMMARY OF INVENTION In accordance with the presentinvention,'interlining is fabricated by applying to a fabric sub-stratea myriad of dots of a thermoplastic resin or other suitable substancecapable of serving, when subjected to heat and/or pressure, of securinga suitably shaped piece of the interlining to a base fabric, e.g. thefront of a suit coat. The invention does not depend per se on thesubstances used for the dots or the mode of adhering the interlining toits companion fabric, but relates to the distribution of the dots in anarray which has a varying density per unit area, depending upon therelative stiffness to be imparted to the various regions.

Where, herein, I employ the term dot, it is not intended thereby tolimit the configuration of the same to a circular outline, and where Iemploy the term myriad, it is not intended thereby to limit theconfiguration of the same to a circular outline, and where I employ theterm myriad, it is intended to convey the idea of a relatively largenumber of dots thereby, impliedly, referring to an arrangement lendingitself to a proportioned variation in density. In lieu of dots in thegenerally accepted sense, the adhesive medium may take the form, amongothers, of a set of lines which are parallel or non-parallel or of twosuch sets intersecting each other. The term sub-strate is intended torefer to the fabric to which the dots are applied, e.g. percale.

Since, as previously mentioned, the dot distribution is reflected invarious degrees of stiffness ofthe interlining which is, in turn,transferred to the companion fabric, the present invention comprehends avariable spacing of dots having a proportioned relation to the desiredstiffness of the interlining at different zones.

For example, interlining for the front of a mans suit coat is preferablystiffer over the chest than at the bottom.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 illustrates a web of sub-stratewith the dots arranged thereon in a proportioned manner, wherefromcoat-front pieces may be cut therefrom crosswise;

FIG. 2 is a view similar to FIG. 1, but with the dots arranged forcutting coat-front pieces therefrom lengthwise; and

FIG. 3 is a view showing a different pattern of dot, namely, lines ofthe adhesivemedium.

DESCRIPTION OF THE PREFERRED EMBODIMENT Adverting to FIG. 1, there isshown a length of substrate 20 of any fabric conventionally used forinterlining, e.g. percale, and superimposed thereon in phantom areseveral outlines 22, along which the fabric will be cut to yield piecesto be incorporated in one side of a coat front. It will be understoodthat interlining is used in many applications, and that the example istypical of one in which the stiffness imparted to the shell fabric isdesirably proportioned from a greater stiffness over the chest to alesser stiffness at the bottom.

To this end and in accordance with the invention, the dots 24 arearranged in equally spaced rows A, B, C, etc. along the length of thefabric and in columns a, b, 0, etc. transversely of the fabric. However,these columns are of graduated spacing from a maximum at the left margin26, to a minimum at the right margin 28. Assuming uniform dot size, theresult will be a greater density of dots at the right than at the left,i.e. the dot distribution has maximum density at the right, and minimumdensity at the left. In this way, the interlining,

when attached to the shell of the coat front, will result I in maximumstiffness of the composite in the chest region and minimum stiffness atthe bottom.

Alternatively, the rows A, B, C, etc. may be nonuniformly spaced toobtain a density of dots which varies in the other direction also, i.e.as one progresses from one side of the garment to the other, i.e. in avertical direction as seen in the figure. To enable a clearerunderstanding, it is to be noted that, in one commercial form ofinterlining, there are approximately 350 dots per square inch, and thateach dot has a substantially circular aspect of about 1/32 inchdiameter. The size and spacing of the dots in the drawing areexaggerated for clarity.

In a broad sense, the invention contemplates a distribution of the dotsto obtain any desired stifiness over any desired zones of the ultimateoutline of the piece of interlining. In this respect, the invention isindependent of the magnitude, configuration or material comprising thedots. However, for special applications, these parameters may be variedalong with or independently of the spacing of thedots.

FIG. 2 is similar to FIG. 1, except that, in this embodiment, the pieces22a are cut from the fabric a in the lengthwise direction. In this case,the columns and rows of FIG. 1 are obviously interchanged and areindicated by the same reference letters. Otherwise, the description willbe clear from what has preceded.

An alternative is shown in FIG. 3, wherein the dots are replaced bystripes of adhesive 31 lengthwise of the fabric and stripes 32transversely thereof. By providing closer spacing of the stripes at theregions where greater density is required and vice verse, the advantagespointed out in connection with FIG. 1 may be realized. It will beunderstood that the stripes 31 may be spaced uniformly and the stripes32 spaced nonuniformly to obtain specialized characteristics, or viceversa. If desired, the stripes may be combined with circular dots.
